The Serinity Flatback Crystals Size Sample lets you order a single flatback crystal in any size from the range covering SS3 to SS48, so you can see how it looks on the garment, accessory or nail you are working on before ordering a full pack. There is also a mixed pack with one of each size, which is the quickest way to compare all the sizes side by side. Samples are sent in Crystal, since the point is to check the size rather than the colour. Why Order a Size Sample Stone sizes are hard to judge on a screen, and the step between one size and the next can be as little as 0.2mm. Laying a real stone on the piece you are working on settles it far quicker than working from a measurement, and costs a fraction of ordering the wrong size in bulk. Our printable crystal size guide shows every size at actual scale if you would rather check on paper first. Serinity, Made in Austria and Finished in the UK Serinity is Bluestreak Crystals' own crystal brand. The crystals are manufactured in Austria, then quality-checked and packaged at our UK facility.
